Objective To investigate the role of ephrin A genes in the development of oxygen induced retinalneovascularization (OIR) in mice.Methods The OIR model was established by oxygen induction in new born C57BL/6J mice.Reversed transcript polymerase chain reaction (RT-PCR) was used to measure the expression levels of ephrin A1-A5 in retinas of mice in experimental and normal control group.Results All of the ephrin A family genes expressed in normal retinas. Ephrin A1 mRNA was significantly higher in OIR group(t=3.19,P=0.019); ephrin A2 mRNA was higher in the 15-day-old OIR retinas(t=3.71,P=0.033）; ephrin A3-A5 mRNA decreased or disappeared in 12 and 13-day-old RNV mice, and increased in 15-day-old OIR mice. Conclusion Ephrin A genes are involved in the development of retina and OIR.
